To all whom it may concern Be it known that I, Ween. PAZAYGHUK, a

citizen of Ukraine, residing at New Castle,

Y in anti-submarine devices,

A entire hull of a ship,

county of New Castle, and aware, and I, WASYL Pa'rz, a citizen of Ukraine, residing at New Castle, county of New Castle and State of Delaware, have invented certain new and useful Improvements in Antisubmari e Devices, of which the following is a sp cation This invention relates to improvements and particularly or fend off subto types adapted to ward projectiles.

marines or other under-sea The principal object of the invention is to' provide a plurality of rigidly supported resilient armor plates, arranged to encircle the whereby injury is prevented from being done the same.

A further object is to provide a novel form of resilient supporting means, so that the armor plates may retract under the impact of a blow, cushioning the efiect of the same with respect to the ship 'to which they are engaged. V

These and other like objects are attained by the novel of parts hereinafter described and shown in the accompanying drawings, forming a material part 0 this disclosure, and in which Figure 1 is a fragmentary perspective view showing a conventional type of ship and the application of the invention.

Fig. 2 is a top plan view, showing a ship and the manner of applying the invention."

Fig. 3 is an enlarged fragmentary side elevational view of the same, and

Fig. 4 is a further enlarged fragmentary horizontal sectional view, taken through the armor supports.

Engaged with hull, are a plurality of horizontal outstanding rigid bars 14, the same supporting an armor plate 15, extending circumjacently around the entire hull of the ship, and which forms the inner protective guard therefor.

The outer guard plate elements 18 adapted to receive the impact, are rectangular in outc lly within the rigid tubular elements 20.

State of Del-I construction and combination gaged with-theends of said bars,

the exterior of the ships- Formed in the tubular elements 20, upon opposite sides thereof, are open longitudinal 'ends so that the tubes will operate in the permitting insertion of manner of springs, the prongs 24 into the slots 23, the prongs acting as limit stops for the amount ofmovement of the tubes22, within the engaging tubes '20, and preventing them from beingpressed outwardly beyond a definite distance by-the coiled compression springs 27 which encircle both of the tubular elements and are adapted to press the plates 18 strongly outward from the inner plates 15.

Thus a double protection for the ship is provided, first, by the resiliently supported outer plates 18 which are in themselves adapted to receive the impact of a projectile or the like, plates 15, thereby preventing damage and it will be readily understood that the plates at ,,the bow or stern of the vessel must be bent-in accordance with the contour of the ship, while the supporting elements remain substantially as described.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is.

1. In an antibination with the hull of a ship and a plurality of rigid bars extending horizontally outward therefrom, of an integral armor plate adjacent to the hull of said vessel, en-

a plurality of tubular elements secured to the exterior of said rigid armor plate, a plurality of independent rectangular armor plates, tubular elements engaged upon the inner sides thereof, said tubular elements being telescopically receivable within the first named tubular elements, means 'for limiting the moplurality of springs encircling bothof said 24, of lugs formed with bmarine device, the comd and second, 'by the inner rigid tubular elements, whereby said movable plates are extended normally outward 2. In an anti-submarine device, the combination'with a fixed guard plate adjacent to the hull of a vessel, of a plurality of tubes secured upon the outer side of said fixed plate, said tubes .containin slots, a plurality of indepen ently rectanfillar armor plates, tubes engaged upon e inner side thereof, said tubes being longitudinal Y movable,

to the exterior of said rigid plate, said tubular elements containing longitudinal slots,

slidably engaged within the first named tubes,- V

shaped openings formed at the outer ends of said inner tubular elements,

lugsformed at the ends thereof,engageable in said "slots, and'springs encircling both of said tubular elements adapted to press said guard plates away from said fixed plates.

7 In an anti-submarine device, the combination with a rigid platesurrounding the ull of a ship, of tubular elements secured independent rectangular armor plates, tu-

= bular elements secured to the inner sides signatures.
